IMPROVEMENT IN METALLIC CARTRIDGES.

Specification forming part of Letters Patent No. 113,634, dated April11, 1871.

To all whom it may concern:

Be it known that I, SILAS ORISPIN, of New York, in the county of NewYork, and in the State of New York, have invented certain new and usefulimprovements in Cartridges; and do declare that the following is a.full,clear, and exact description thereof, reference being bad to theaccompanying drawing, and to the letters of reference thereon, making apart of this specification.

The nature of my invention consists in a solid metallic disk forcartridges for breechloading lire-arms and a cap and anvil chamber orreceiver made in one piece, and constructed so as to admit of the bodyof the cartridge being secured to it by means of a wad; and also in asolid metallic disk and cap-chamber made of one piece of metal, incombination with a tubular cartridge-case, when secured thereto by meansof solder, either on-the out side or inside, all of which will behereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make. and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in Which-Figure l is a longitudinal vertical section of the cartridgeshell,showingthe disk and capchamber in position before the wad is put in.Fig. 2 is a similar View, showing the wad in position. Fig. 3 is asimilar view, showing the disk attached to the cartridge-shell by meansof solder on the outside. Figs. 4 and 5 are similar views, showing twoways of applying solder on the inside.

A represents the body, case, or shell of a cartridge, made ofpaper,metal, linen, or any other suitable material, or of two or more materials combined.

B represents the base of the cartridge, formed of a solid metal disk,from which is set up, and without breaking, the continuity of the metal,a seamless tube, chamber, or pocket, I), for the reception of the capand its anvil or other means of ignition, said tube having a rent at itsend, as shown in the various figures.

This disk, with its cap, pocket, or chamber, is secured to the shell orcase A in various ways.

After the tube or pocket has been inserted in the end of the shell, awad, a, of paper, metal, or other suitable material, is inserted withinthe shell and surrounding said tube. This wad is then, by means ofpunches and dies adapted to the purpose, forced home, and at the sametime the end of the tube b is pressed so as to form a bulge or shoulderabove or on top of the wad, as shown at m, Fig. 2, whereby the base,shell, and wad are firmly and solidly united together; or, in place ofthe wad a, solder may be poured on the outside, all around between thedisk or base B and the end of the shell, as shown at y, Fig. 3; orsolder may be poured into the shell, as shown at z, Figs. etand 5,thereby uniting the shell with the tube b.

It is obvious that in this case one or more grooves, 'i, may be formedin or around the outside of the tube 1), as shown in Fig. 5, into whichgroove or grooves the solder, when poured into the shell, will pass, andthus form an additional security.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. A solid metallic disk and a centrally inward-projecting cap and anvilchamber or receiver, made in one piece, in combination with aninternally-flanged tube or cartridgebody, when secured thereto by meansof a wad, as described. I

2. The metallic disk B and cap-chamber b, made in one piece, incombination with the rear end of the cartridge-body A or its reentorce,when secured thereto by means of solder, substantially as herein setforth.

In testimony that 1 claim the foregoing I have hereunto set my hand.

SILAS OBISPIN.
